Wastewater Pure Oxygen Injection

PURE OXYGEN INJECTION FOR WASTEWATER TREATMENT

For the treatment of municipal wastewater tanks or facilities with much smaller volume and footprint than air-fed sludge plants, turn to Mazzei. Using pure oxygen allows for much higher oxygen uptake rates (OUR) to be sustained than when air is used. In a Mazzei pure oxygen injection system, wastewater is pumped through one or more high efficiency Mazzei® venturi injectors, forcing oxygen to aspirate into the wastewater. The resulting gas-water mixture is discharged back into the tank/facility through Mazzei MTM™ mixing nozzles and nozzle manifolds for greater oxygen transfer. No blowers are required which reduces energy costs and noise. For high dissolved oxygen requirements, Mazzei’s Pipeline Flash Reactor™ can also be utilized.

BENEFITS OF MAZZEI FOR OXYGEN MIXING AND CONTACTING:

Small Footprint

No Limits on Water Depth

Low Operating and Installation Costs

Energy-efficient Oxygen Transfer

Subsurface Injection of Oxygen to the Bottom of the Tank where the Head Pressure of the Water Column Facilitates Higher Oxygen Solubility

Very High Oxygen Utilization Rates

The Ability to Feed Oxygen Selectively into the Various Stages to Optimize the Treatment Process

Very Fine Regulation of Dissolved Oxygen Levels in the Wastewater to Prevent the Growth of Nocardia Microorganisms, which Cause Severe Foaming Problems in Conventional Pure Oxygen Plant Configurations
